Buddypress - Limit Blog Excerpt on Activity Stream - buddypress

Question

I'm using the following code to limit the number of words that appear on my blog pages.
function custom_excerpt_length( $length ) { return 32; } add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );
I need to limit the number of words that appear on the BuddyPress Activity Stream when someone creates a blog post. Currently when someone creates a new blog post, the excerpt appears on the Activity Stream with about 50+ words. I need to limit this to around 32 words.
Does anyone know how to accomplish this?
Thx

This is what I'm using. The first part limits the text, the second part ensures the thumbnail is present. Thank you shanebp for pointing me in the right direction.
function 5_activity_content_body( $content, $activity ) {
$content_length = 42;
if ( 'new_blog_post' == $activity->type ) {
$images = extractImageFromContent($content);
$_content = (strlen($content) > $content_length) ? substr($content, 0, $content_length).'...' : $content;
if(!empty($images)) {
$_content .= implode("", $images);
}
return $_content;
}
return $content;}
add_filter( 'bp_get_activity_content_body', '5_activity_content_body', 10, 2 );
This brings the thumbnail back.
function extractImageFromContent($html) {
preg_match_all('/<img.*?src=[\'"](.*?)[\'"].*?>/i', $html, $matches);
return ($matches[0]) ? $matches[0] : array(); }
